Bad.
The original was much better. The graphics in this one are good. The music is great. But the gameplay is severely lacking. It took me 5 days just to kill one person. Even after I had pooled all my points into upgrades, which is extremely hard due to the amount of points you are given each round. It takes up points just to do anything and even then when you have spent your points on an action it turns out to be a big waste. Then of course there is the part where the humans you infected just suddenly become cured. Even though none of the countries had developed even 1/5 of their cure and the effectiveness of my virus was pretty damn good. You can't even call this a "spin-off" it's more of a mockery. I could keep on stepping all over this thing but I think I'm gonna go play the original Pandemic to reassure myself that the original is much better.
